Now the thread is pulled but fortunately Gunner was thoughtful enough to archive it for us. So I'll just put it over here and no one will notice.
"I am interested. Do the slaves die there? Do they never come back? Do they stop being slaves when they are done as children? What do they eat on their 20 year trip to Mars. Who guards them? What exactly are they doing for their slave masters?"
(Not necessarily in the order posed.)
The trip to Mars doesn't take 20 years. It only takes a few days. But they are kept there 20 years, eating surplus C-Rats, K-Rats and MREs.
When their time on Mars is up they are young adults, between 25 - 35. They are given a "brain wipe" and reintegrated into society in urban areas working as Community Organizers, Graffiti Artists and bloggers.
A few who show exceptional adaptability are given the "Manchurian Candidate" treatment and called out when needed for false flags such as Aurora, The Charleston Church, and Sandy Hook.
As for their work on Mars, they are engaged in mining. They dig deep into the Martian Crust extracting a material known as "Unobtainium" which is a key component in replacement parts for vintage autos such as pre 1975 Lincoln Continentals, Studebakers, Packards and Opel Kadetts.
A very few of the Elites are given careers in the DC area as pizza makers and ping pong coaches. One such Elite broke away and is now a personal hairstylist for Giogio Tsoukalos.
(On Mars the lower gravity makes it a lot easier to get that "elevated" look.)
I note that you conveniently dodge the question “do they die there”.
I would think the mortality breakdown would be highly relevant.
